Eagle Star Minerals has reported that the results of the composite interval channel sampling program has confirmed the occurrence of mineralized phosphate within the 7 m mineralized package across the 15 km defined strike region. The company is waiting for additional results.
Chemical and Metallurgical Tests (solubility)
The area lies less than 20 km towards Picos’ northern part in Brazil. Pico city is located at the center of the state and has good infrastructure that includes proximity to railroads and huge agricultural centers. The future beneficiation method can obtain water from the Bocaina dam lying at the center of the concession block. The Canabrava Block encloses 40,678 ha across 23 mineral claims.
The composite channel samples combine the low-grade siltstone and high-grade sandstone into an average result. The company has planned to isolate both materials with the help of a common mining method, enabling separation of high-grade and homogeneous fractions to 28% P2O5 of SSP standard grade and utilization of lower grade by product as a natural fertilizer.
Currently, the company is carrying out metallurgical and chemical tests with an aim to identify solubility. The chip sample results, which represent the types of mineralized rock, are expected to be received by mid-July. Encouraging results of solubility depends on the characteristics of the rock. Sedimentary rocks represent higher solubility of phosphates when compared to crystalline rocks. Brazil-based SGS Geosol Laboratories carried out analytical work at its Vespasiano plant.
